Abstract

An AND gate has a signal input to which a periodic signal is applied and a control input to which a control pulse is momentarily applied. In response to the concurrent presence of the periodic signal and the control pulse at the respective inputs, a periodic signal is provided at the output of the AND gate. The periodic signal provided at the output of the AND gate is detected for charging a charge storage means to a voltage level of substantially the same level as the voltage level of the control pulse. This latter voltage level is fed back to the control input of the gate, and in response thereto, the gate continues to provide the periodic signal at its output after the control pulse terminates and until the periodic input signal to the gate is interrupted. The periodic output signal from the gate is amplified in an amplifier and provided as the output signal of the latch circuit. In response to the sensing of the AND gate no longer providing the periodic output signal, the charge storage means then rapidly discharges through the amplifier.
